Marca have reported that both capital city sides will follow in Barcelona’s lead and not be allowed to sign players for two windows.
Barcelona were recently prohibited from signing players for breaking the rules associated with recruiting young players and as such will not be able to strengthen their first-team squad this summer.
However, with the two capital city sides now in the officials’ gaze, the report states that both Madrid club are set to be handed similar punishment for the same offence.
This would reportedly start this summer and last for two transfer windows, meaning that neither Diego Simeone or Carlo Ancelotti’s men would be able to add to their squads until the summer of 2016.
Fifa are reportedly ready to hand down the sanctions, in what would be a major blow for both clubs.
If this does come to fruition it would be good news for a number of Premier League clubs, who have seen their best players linked with Real Madrid in recent times.
With the Clasico sides so dominant in Spanish football and Atletico a shock title winner last season, the sanctions would give teams like Sevilla and Valencia a real chance at closing the gap.
